NO. 3382 GENUS ENTOMACRODUS — SPRINGER 71 



a strikingly different color pattern; from E. t. thalassinus, E. sealei, 

 and E. caudojasciatus, in having the entire ventral margin of the upper 

 lip crenulate, and in having more gill-rakers, usually more pseudo- 

 branchial filaments, and more than one pore before each anterior 

 nostril. 



Distribution (fig. 6). — E. niuafoouensis is known from Mada- 

 gascar, Bonin, Marianas, Tonga and Niuafou Islands.

Plate 11 



DescriptiOxV. — (Characters for holotype given in parentheses.) 

 Segmented dorsal fin rays 15 or 16 (16) ; segmented anal fin rays 16 or 

 17 (17); posteriormost anal pterygiophore supporting 1 or 2 external 

 elements (supporting 1 element in 7 of 11 specimens; supporting 1 in 

 holotype); total gill-rakers on first arch 21-24 (23); pseudobranchial 

 filaments 7-10 (7) ; vertebrae 34 or 35 (34 in 8 of 9 specimens; holotype 

 with 34) ; supraorbital cirri 4-8 (5, too few specimens available to 

 determine if cirri or predorsal commissural pores increase in number 

 with increase in size) ; main, or longest, supraorbital cirrus with all 

 branches mesially; nape with 1 cirrus on each side; predorsal commis- 

 sural pores 9-42 (21 in holotype; 9-21 in 9 specimens 39-72 mm SL; 

 42 in specimen 87.5 mm SL) ; preopercular series of pores with at 

 least 4 positions with pairs or multiples of pores (6) ; 1 pore before 

 each anterior nostril; lateral line terminating on side of body in area 

 below and between dorsal fin ray 10 and point just posterior to level 

 of posteriormost dorsal fin ray (below dorsal ray 10) ; ventral margin 

 of upper lip completely crenulate; lip crenulae number 24-32 (28). 



Proportional measurements: See tables 3, 4, and 29. 



Of the 11 specimens available, the largest, 87.5 mm SL, was a male 

 with the anal spines and first two anal rays covered with fleshy 

 rugose modifications of the skin, indicating probable sexual maturity. 



Color pattern of holotype. — (None of the specimens available 

 were in good condition and for the most part color pattern was in- 

 discernible. As far as could be recognized, the color pattern of all 

 the paratypes appeared to agree in all essentials with that of the 

 holotype.) There are six areas on the side of the body bearing ir- 

 regular bandlike dusky marks. The area on the caudal peduncle 

 consists of a pair of spots arranged one over the other. The next fom' 

 areas anterior are each dusky X-like markings, darkest midlaterally, 

 palest ventrally. These marks do not reach the ventral body contour.
